This actually happened to Evernote. They took the advice of “keep talking to your customers and ship whatever they want” as the only guiding principle for product development. And what ended up happening was paying users liked it, but the product become unintuitive and feature overload for the new user. To the extent that they had to rebuild a version for the new user. Users don’t always know if they really want something. It’s your job to take the extra step to think on their behalf: whether they really need this. Or can what they ask be done through something much simpler. Or can you solve multiple problems of different users with one new redesign rather than a bunch of changes. The right principle is: “Keep talking and listening to your users, spend the additional time thinking on their behalf what they actually want, and ship that”.
